Going on Holiday?
- Turn your appliances off at the wall - even appliances on standby use energy!
- Turn your heated towel rail off.
- Sensor lights are great outside, they only turn on when needed and provide additional security for your home while you are away.
- Turn the hot water cylinder off if you are going to be away for more than one week.
- If you have a fridge that you won't need to keep things chilled in, turn it off at the wall, but remember to leave the door open.
These things can make a big difference, for no cost
- Use natural warmth from the sun as much as possible to dry clothes instead of the dryer. SAVE $40* every year.
- Washing powders are so effective in cold water these days, there's really no need to do hot washes. SAVE $60* each year.
- Got a beer fridge? If you only turn it on at the weekend and keep it switched off during the week, you'll SAVE $100* every year.
- For Electric Hot Water cylinders, the Ministry of Health recommend a temperature of 60 degrees Celsius or higher to prevent the growth of Legionella bacteria. Every 10 degrees C higher than that, and you're spending a hefty 10% more than you need to. SAVE $30* every year.
- Like your towels warm and dry? Your heated towel rail can do the job in just a couple of hours - then flick it off and you'll SAVE $100* each year.
